, 17 further means are employed to moor the boats to the main frame and at the sometime to prevent any slacken ing in the said cables from variation in the'ci'irrent or the action of the wind and waves and to hold the motor Wheel more steadily than would be possible by cables alone. This device is a frame consisting of side members 24, connected .hy transverse bars 25. The lower ends of the side members are prorvided with boxes 26 t en...

through which the wheel shaft 19 passes and the upper ends are secured to the uprights of the main. frame by pivot bolts 27. and tie, and at. the same time allows the wheel and sup,- pin-1H to rise and failwith'wavu or iide.

l haveillustrated in Fig 2 a modified form of paddle wheel which will render the hon ts ur- Otiiii iii unnecessary. the wheel itself being constructed so i s to he buoyant enough to he supported in the water without the usnoisnid limits.
